Anick spaces are closely connected with both EHP sequences and the study of torsion exponents. In addition they refine the secondary suspension and enter unstab

In this work the author lets be an irreducible root system, with Coxeter group . He considers subsets of which are abelian, meaning that no two roots in the set

The author discusses in which sense general metric measure spaces possess a first order differential structure. Building on this, spaces with Ricci curvature bo

The authors introduce and study the class of groups graded by root systems. They prove that if is an irreducible classical root system of rank and is a group gr

The authors give the complete stably rational classification of algebraic tori of dimensions and over a field . In particular, the stably rational classificatio
